Changed ... postfix's default is 550, but we had:
unknown_local_recipient_reject_code = 450
Funny thing is, looking on google, this isn't that particularly unusual:
"On my Fedora Core box the following settings and comments were in
main.cf
# The default setting is 550 (reject mail) but it is safer to start
# with 450 (try again later) until you are certain that your
# local_recipient_maps settings are OK.
#
#unknown_local_recipient_reject_code = 550
unknown_local_recipient_reject_code = 450"- <http://www.webservertalk.com/message1926259.html>
I suspect that that is what I did when I set things up originally, went with
the 'safter to start with 450', but didn't go back and change it to 550 ...

Fixed, now MX 0 == mail.postgresql.org, also an A record ...

Fixed ... I had missed the mx3 IP in the mynetworks file on postgresql.org ...
the other 3 mx servers should never have been affected, only the offsite one ...
